Abstract

The embodiment of the invention relates to a method and device for acquiring position of a transmitting antenna. The method comprises the following steps: acquiring the error rate of the signals of all transmitting antennae received by a mobile station at the located position; acquiring the domain average error rate of a cell in which the mobile station is located according to the error rate of the mobile station at the located position and the probability density function of the mobile station on the position; and acquiring the position of the transmitting antenna by minimizing the domain average error rate. The embodiment of the invention has the advantages that the problem of how to arrange the transmitting antennae in a two-dimensional cell to achieve the system performance optimization is solved, and the mobility of the mobile station is taken into consideration.

Description

technical field [0001] Embodiments of the present invention relate to the communication field, and in particular, to a method and device for acquiring a position of a transmitting antenna. Background technique [0002] Distributed antenna system, as the mainstream solution of the next generation mobile communication system, is receiving more and more attention. In a distributed antenna system, multiple transmit antennas connected to the same base station are distributed in different geographic locations in a cell. How to increase system capacity and improve coverage quality by rationally arranging these transmitting antennas has become a key issue in the design of distributed antenna systems. [0003] The prior art provides a method of arranging transmit antennas through stochastic theory. In this method, the arrangement of each transmitting antenna is regarded as an independent uniform distribution process, and this method evaluates the scheme of randomly arranging transm...
